Question: Write the estimated equation for this analysis with the y-intercept, regression slope, and the variables. Round the coefficients to 2 decimal places. (4 points) Regression

  1. Write the estimated equation for this analysis with the y-intercept, regression slope, and the variables. Round the coefficients to 2 decimal places. (4 points)

Regression model equation: Y = a +bX OR (Y =B0 + B1X= Error)

Estimated Equation: finger-wrist tapping test (fwt_r) = 64.64 + -0.42 x Blood lead level (Id73)

  1. Using the formula in the previous question, compute the predicted finger-wrist tapping score if a child had a blood lead level of 30 micrograms/100ml. Round the predicted value to the whole number. (4 points)

finger-wrist tapping test (fwt_r) = 64.64 + -0.42 x Blood lead level (Id73)

? = 64.64 - (0.42 x 30 micrograms/100ml)
